This question is about Austrian law.
Imagine there is a real estate agent, who helps people buy and sell properties. Many of his elderly clients
- sell the property they have,
- with that money buy a flat in another place
- in order to live closer to a hospital.
Imagine there is a place far away from the next hospital and there is a doctor in that place.
Is it legal for this doctor to put a billboard in his office with ads of places with better access to hospital (i. e. places, where his senior clients can move to, if they buy the services of the real estate agent) ?
